2) No More Death Stars
One of the weakest aspects of Star Wars: The Force Awakens was the fact that it essentially brought back the Death Star, albeit in a different form. Both this instalment and the next one need to move away from that, giving The First Order some other sort of grand plan to take over the Galaxy.
With the Senate wiped out, a greater focus on the villainous group establishing their dominance would be vastly more interesting than a construction of a superweapon, especially as a huge number of troops and ships should be more than adequate to take over instead of them relying on a weapon of mass destruction.
If Rian Johnson has dreamed up something which is totally new and original, that’s fine, but the movie building up to the introduction of yet another Death Star like device in this film or Episode IX would be downright eye roll worthy, especially coming off the back of Rogue One, which was all about stealing the plans to the original. It’s time for both the villains and the franchise as a whole to move on from planet killing weaponry.
